IMPROVEMENT IN CULTIVATOR AND PLOW COMBINED.

l Specification forming part ol' Letters Patent No. 8 M054, dated August 11,1868- To all whom it may concern Be it known that I, Lnwrs R. WRIGHT, ot the city of Troy, in the county of Rensselaer and State of New York, have invented a new and Improved Combined Cultivator and Plow;

and I do hereby declare that the following isl hereinafter fully described and set forth. Fig.

2 is a top view of mysaid cultitator and plow, more clearly showing the construction of the various parts thereof', as hereinafter more fully Fig. 3 a view of one of the standards, which is attached to the frame ot' the cultivator, and to which standard is attached the tooth of the cnltivator, substantially-as shown in theaccompanying draw'- ings, and more fullydiereinafter described and set forth. Fig. 4 is a front view of one ofthe cultivator teeth, more fully hereinafter described. Fig. 5 is a perspective view of one of the standards with the tooth removed therefrom and showing the bolt by which the said tooth is attached thereto, as hereinafter fully described and set forth. Fig. 6 is also a perspective view, showing the centerstandard and tooth, and also showing the plowand the man- 'by dotted lines at Fig. 6, so as to allow a lateral movement to thesaid mold-board to regulate the width of the furrow, substantially as hereinafter described and set forth.

' It also consists in the use and employn'i'ent of the double moldboard B C, so constructed and hinged together as to allow the raising and lowering of the larger section ot' the said moldboard B by means of the slotted arms I) D, whereby the height ot'thc furrow to be ont may be regulated and determined, substantially in the manner and for the purposes hereinafter fully described and set forth.

lt alsoconsists in the use and employment ol' a triangular-shaped standard consisting ot tlie.tooth.bed and uprightE and brace F, al1

cast in one solid piece, whereby great strength is obtained,combined with lightness of material, substantially as hereinafter described and set forth.

1t also consists in the use and' employment of the six-pointed curved tooth H, in combination with the triangular-shaped standard E F, substantially in the manner and for the purposes hereinafter fully describedland set forth.

To enable others skilled in the art to which myinvention relates to make and usethe same, 1 will here proceed 'to describe the construe tionand operation thereof, which is as follows, to wit:

The frame A of my said cultivator and plow I design to make ot' some hard wood that will answer the required purpose, and of the usual form, and of any size and strength required or deemed best. l v,

l I are handles, which are securely fastened to the frame A by means 0f the screws a a, Fig. 2, and the braces b b, Fig. 1, and which said handles are for the purpose ot guiding and working the said plow, and are iliade of wood, of the usual size and construction.

The standards E F, dre., are designed t-o be made of malleable iron, and are securely fastened to the frame A by means of the screws and nuts e e, &c. The projectionsff, &c., on

the standards, which are shown at Figs. 3, 5,'

. and ot' form and construction substantially as shown in the 'accompanying' drawings. The

teeth are made pointed at both ends, so as to be reversible, and by being made curved, as shown in the drawings, the earth can be more completely displaced and cultivated than by the use of any other teeth heretofore in use'. The said teeth H II, &c., are securely fastened to the standards E F, &c., by means of a nut andscrew,g, Fig. 5, or anyother means thought best to use.

rlhe standard directly under the arms I I,'and marked E',- I call the center standard, 7 and to this center standard I hinge the two sections ofthe mold-board, (marked (5,) which allows the free working of the same, fothe purposes hereinafter described.

The main parts of the mold-boards B and B are fastened to the sections C and C by means of nuts and screws, and the upper nut works in a slot, 71, in the said mold-board B, whereby the said mold-boards B and B may be raised and lowered at pleasure, or as it is desired to regulate the height of the furrow to be cut, when the said plow is in operation. rEhe said mold-boards B and B are held in any desired position by me'ans of the slotted arms D D, Fig.`1, which are fastened to the fratne A by means-of the nuts and screws 7.2 7.'. (Shown at Fig. 2.

LL, Flg. 2, are slotted arms'running across the top of the frame and held in position by the thumb-screw l, (shown at Figs. 1 and 2,) and which thumb-screw is fastened to the cen-v ter frame-piece, A. These slotted arms L L and thumb screw l are for the purpose of regulating the distance between the moldboards B and B', whereby the width of furrow to be cut is as herein before described. Tile said moldboards B and B', or sections thereof, C and C', being hinged .t0 the center standard, E', allows tite fretworking ot' the said moldboards B and B laterally, while tite slots lt It, Figs. l and 6, allow the said mold-boards B and B to be elevated or depressed as required, thereby regulating the height of the furrow to be cut, substantially' as hereinbefore described. lhe frame-pieces A A are hinged or loosely rivetedto the center frame-piece, A', at- N, Figs. l and 2.

At M, Figs. l and 2, nin-y be fastened any 'suitable device for the purpose of fastening the horse -or'horses to said plow and cultivator.

lhe arms b b, nuts and screws 6,11, I, and r, and slotted arms D D-and L L, may all be made ofcast-iron and'ofany size, shape, and strength that will best answer the required purpose.

If desired to use the eultivator and not the plow, the plow maybe readily removed by displacing the nut and screw o, Figs. l and 6, and the nuts and screws 7c k, Fig. 2, when, it will be readily seen, the mold-boards may be easily removed; or, if desired to use th-e plow alone, the teeth and standards may be readily removed, as will be seen by reference to the accompanying drawings.

Having thus described the nature of my said invention and improvements, what "I claim, and desire to 'secure by Letters Patent ot the Unitedv States, is-

1. The double mold-board B and U, so hinged and connected together that the main part of said tnold-board B may be elevated or depressed at will, according tothe height of furrow desired to cut, substantially as fully hereinbefore described and set forth.

2. The hingiug of the sections of the moldboard C and- C' to the center standard, E', whereby a lateral motion may be given to the mold-boards B and B' to regulate the width of furrow to be cut, substantially in the manner and for the purposes more fully hereinbefore described and set forth.

3. The slotted arms or their equivalents, D l), in combination with the mold-boards B and B', substantially in the manner and for the purposes herein described and set forth.

4. The upright or tooth-shoe E, incoinbination with the brace I", or its equivalent, all cast in one solid piece, substantially in the manner and for the purposes herein fully described and set forth.

5. rlhe curved reversible tooth II, in combination with the tooth-shoe E and brace F, each being constructed and operated substantially in the in-.tnner and for the. purposes hereinbe- `fore described and set forth.

In testimony whereof. I have hereunto set my hand this 25th day of March, A. D. 1868.
